Rock drill is used in mining mechanical engineering products, mainly used to mine stone, drill hole in the rock, and then put explosives in the hole to blast the rock, so as to complete the rock mining or other stone works, so people also called the drill for the destructor.
According to the power source, the drill can be divided into four types: internal combustion type, pneumatic type, electric type and hydraulic type.
Internal combustion type USES the principle of internal combustion engine, through the combustion and explosion force of gasoline to drive the piston impact steel drill, chisel rock, usually in the construction site no power, no gas source, the selection of internal combustion drill.
Pneumatic type is also referred to as the pneumatic drill, it is the compressed air as the source of the impact drilling machinery, if the propulsion can be divided into air leg type, handheld type, guide rail type, telescopic upward type.
The power source of the electric type is electric power, so there is no need to establish a compressor station, not to mention auxiliary pipes, good sanitary conditions, low noise, strong weight and flexible mobility, which will not affect the health and safety of rock drill workers.
Hydraulic type is using high pressure oil as the power to push the piston impact
drill, and has an independent rotary mechanism. Similar to the pneumatic drill, but relative to its piston diameter is small, the length is larger, the waveform is better.
